MACHINE FOR OPERATING UPON.v HEELS.

Application filed March 5, 1920.

To' all whom t may concern.'

Beit known that I, FREDERICK Jl BALcoM, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain Improvementsl in Machines for Operating Upon Heels, of which the following description, in connection with the accompanying drawings, isa specification, lilereferencevcharacters on the drawings indicating like parts in the several-figures.

This inventionv relates to apparatus for operating upon heels, itconcerning more particularly heel-priclnng,machines These are commonly provided with a feeding instrumentality, as an oscillatory lever, which is adapted'to carry a-heel'into co-operation withthe mechanism, as' the. pricking awls and clamping follower, by which it is to be acted upon. Sometimes heels are over-fed yby the lever, they being advanced by their momentum beyond the point atv which. its oscillation is reversed to return-for the succeeding. feeding= operation. In such cases the forl, which centers the heel before it is clamped for pricking, may not engage it properly, causing it to-be so held that the awls enter incorrectly, or even breaking the forl. An object of this invention is to prevent this over-feeding action, insuring the perfect delivery of each heel to the mechanism which is to operate upon it.

A feature ofthe invention, leading to the attainment ofthe above objects, consists in means for feeding a heel over a support to the mechanism by whichit is to be acted upon, combined with novel means movable along'the path ofthe heelin the operation of the machine feed'for limitingthe feeding movement ofl said heel, which is th-us retained in the desired position. This movement-limiting means may have a bodily movement with-the feeding means,and, re-

gardless `of the manner of support of the heel, IA preferably move t-he limiting means out of the path of the heel afterit has performedits limiting` functiom'it being connected to a relatively fixed point to control it in'this and other actions. The movement-A limitingnieans is shown as yieldable. inthe direction of feed,:it thereby being adapted to accommodate itself to the work, .especially in' disengagement. In the machine for prickingheels which I'have illustrated, the feeding lever has associated means for temserial No. 363,494.

porarily retaining the heel fed in proximity to it. This retaining means I prefer to provide in the form of an-arm, pivoted to the lever and articulated: to a fixed portion of the machine by a link. rIhis arm or retaining means, Iin the reverse movement. ofthe feeding lever when the heel is=released,lmay be made yieldable to facilitate this by'the provision of aA slot-and-pin connection between the lever and the arm, with theconnection under the influence of a spring.

The heels operated upon by the machine may differ considerably inv theiry dimensions, and, to-cause the different sizes to be acted upon properly by the movement-limitingl means in its movement, a further feature of my invention resides in adjustable means arranged to permit the relative movement between the feeding meansand the limiting means to be determined. By. this expedient the limiting effect may be exertedI at the right point, whatever the size of the heel fed. Herein this variation is provided in the length of the limiting means, and with this means connected to a relatively fiXed'point, the length of the connection should also'be changed. The heel-pricking machine which I have illustrated has its retaining arm" joined to the feed-lever constructedl in sec'- tions variable with respect to one another, and with the connecting link forA the arm also preferably thus arranged.

My invention is illustrated in the accompanying drawing as appliedto theel-pricking machine such as is' disclosed in Patent No. 1,234,384, dated July 2li, 1917, andfissuedv to J. I-I, Pope.

Fig; l ofv the drawing being*v apartial transverse sect-ion through such-a machine. taken just at one side o'f thefeedin'g mechanism; andy Fig.v Q, an enlarged detail view of the retaining arm and its connecting' link.

Across the base l0 of the machine extends asupporting surface or way l2, alongy which heels,y indicated' at H, are` fedto the right? as the machine is viewed in Fig. lv of the drawing, from a receiving position, shown in dotted lines, in which they areplaced by the operator, toa positioniin 'which-they are.' acted uponby'the prick-ing mechanism, this appearing in full lines. In the latter posin tion they are alined'with the openings of ai templet 14, through which openingsfpass" pricking awls mounted upon a reciprocatory block 16. In the pricking position the work is centered for the operation, prior to its clamping against the templet by the follower (not shown), through the agency of a fork 18 mounted toslide vertically in a frame 20 rising from the base. Thisy fork is reciprocated by suitable mechanism, as in the patent previously mentioned, from the elevated position illustrated, in which the work is fed, to the centering position, in which the fork contacts with the heel to position it. Pivoted at 22 upon the frame 2O is a feeding lever 24, oscillated by a link 26, bell-crank28 and slide 30, all as described in the Pope patent. The termination of the forward stroke of the feeding lever may be adjusted by a variable pivotal connection 32 between the bell-crank lever 28 and the slide 30, and also by changing the normal angle of a section 34 of the lever 24 by means of a screw 36so that its contact end 38 advances each heel supplied by the operator tothe desired pricking position. At this time, if the heel remains in contact with the feeding lever, it is substantially in correct alinement with the templet, and is so related to the fork that the juncture of the arms of the latter lies at or near a vertical axis through the heel, so that, when the fork descends, it may readily move the heel to the exact point desired with relation to the templet. There may, however, be sufficient -impetus imparted to the heel by the lever to throw it beyond the stopping' point, in which case the end of a fork-arm may engage the top of the heel and clamp it out of the true pricking position, or the fork may be injured by the contact. This I prevent by the movement-limiting means now to be described.

Extending horizontally from the side of the feeding lever portion 34, at a point above the tops of the heels which it feeds, is a pivot pin 40, preferably surrounded by an anti-friction roll 42. This roll operates in a slot 44 extending longitudinally near one end of an arm 46. Near the opposite end the arm is articulated at 48 to a `link 50, the other extremity o-f the link being pivoted at 52 to a relatively fixed point, as a portion of the frame 20. Preferably, the arm 46 is held yieldably, with the bottom of the slot 44 against the roll 42, by a helical spring 54 uniting the pin 40 with that furnishing the articulation 48. vWhen the feeding lever is in the receiving position shown in dotted lines, the arm 46 is raised by the pull of its connecting link 50 into a position considerably above the path of the heels. As the feeding lever oscillates to carry the heel to the pricking position, the arm 46 advances with it, but more slowly, since it is at the same time directed downwardly by its link. The lengths of the arm and link and their pivotal connections are so related that when the lever 24 reaches its eXtreme of feeding movement, the lower curved extremity 56 of the armV 46 comes into contact with or in close proximity to the upper portion of the side of thel heel opposite that upon which the portion 38 of the lever bears. Becauseof the engagement v of the arm with this opposite side of the heel, it cannot be moved by its momentum beyond the point at which it may be correctly engaged by the fork 18. So, when this descends, its centering` contact with the heel is assured. Upon reverse movement of the feeding lever, in preparation for the advance of the succeeding heel, the contact face 56 is raised above and out of the path of l posite direction. For this purpose, said arm is provided with an end section 58, having lin it a longitudinal slot 60, through which extend screws 62 threaded into the main f portion of the arm and serving to clam the section 58 by the contact of their hea s with it. The controlling link 50 is similarly variable in length, it having a lower end section 64, into which are threaded screws 66 passing through a longitudinal slot 68 in the body portion of the link. To adjustvr the armand link for any particular size of heel to be operated upon, after the lever portion 34 has been arranged to give the desired feeding stroke and 'with this lever portion in its extreme heel-advancing position, the securing screws of the end sections of the arm and link are bot-h loosened, the surface 56 carried into correct relation with the heel, and the sections clamped by their screws.
